Apparently not everyone is well-versed in Johnny Cash's iconic country music repertoire, a sad truth made obvious by a contestant on Thursday night's (Jan. 10) episode of 'Wheel of Fortune.'

With only a handful of letters missing from the puzzle board, the befuddled contestant confidently attempted to solve the rather obvious 'Song/Artist' puzzle... only to make one of the most epic fails in the history of the long-running game show.

'I Have the Wine' is clearly not one of Cash's songs, but given the woman knew well enough to include Cash's name in her answer, the public flub could very well have been a result of camera fright. Maybe. We hope. After all, 'I Walk the Line' inspired the title of a recent blockbuster flick -- 2005's 'Walk the Line' -- that earned A-list actress Reese Witherspoon her first Academy Award for Best Actress for her portrayal as the iconic June Carter Cash.

What did we all learn from this very embarrassing mistake? It pays big to be a fan of the Man in Black!
